When I bought my DLP I knew that I had no need to wall mount and therefore no reason to restrict myself to flat panels. I couldn't be happier with my purchase.
What I find funny is that most people don't wall mount their TV and really a DLP doesn't require much more table space than an equivalently sized flat panel.
Exactly. I couldn't be happier with the 56" Samsung we bought 2 years ago. It's been nothing but a pleasure and definitely at the time I couldn't have gotten anything nearly as good in the same size range without paying nearly double.
I also really love the picture quality- to my eye, a DLP has a subtle 'softness' to the image that's non-pixely, but still razor sharp for HD images. I dare say that even crappy SD images look the best they're ever going to on a DLP compared to any other large format which will be much less forgiving.
Like you say, if not wall mounting, and depending on the space, a flat panel doesn't really matter. In my setup, I'd merely have a bigger gap between the back of the TV/entertainment center and the wall for dust to collect.
